Trivial Psychic:
So I've been playing through various TBP campaigns, and have been thoroughly enjoying the Fortune Hunters. I've been playing on latest Nightly builds, but when I get to the 4th mission in 2261 (the "0" mission doesn't count), I get a "Failed to Load" error. I ran a debug build and got the following error, enhanced slightly from the better details provided by the error message FRED gave me:

Error in mission event "Explosions Random":Not a Number

Warning: Not a number.

In sexpression: ( every-time-argument

From the looks of it, it doesn't like <argument> as a number. I looked up the variable "@eff" and it's a string variable so it shouldn't be complaining anyway. I did a check through earlier Nightlies and found that this bug (assuming it is) was introduced in time for the October 30th build. The Oct. 28th build doesn't complain.

0rph3u5:
I think, that's an old FRED bug with the modify-variables SEXP saving the modification for string variables wrongly (it has been fixed) - the fix for a mission saved incorrectly like that, is to add quotation marks manually to the SEXP via text editor, and then the mission should work correctly again

EDIT: That's how modify-variable applied to string variable should look like

--- Code: --- ( modify-variable
"@Loadout_G3S2[MX-50]"
"<argument>"
)

--- End code ---
